A curious question, SIA is currently offering complementary booking change. What happens when you are booked on a fare type that is not allowed to be cancelled and then change to a fare type which is refundable?
Economy lite change to economy flexi, will the full fare be refundable or only the fare difference paid during the upgrade?
